How many times have you wished you could go back in time to the moment you took a photo... after transferring it to your computer and noticing it was out of focus?
After centuries of minor advances in the photography field (although we now use digital image sensors, the exact same principals go back to the days of the first photos) it looks like we're about to leap ahead.
What if you were able to change the focus point of the photograph... at any time after taking it?
That's exactly what you'll be able to do with Lytro cameras.
Instead of capturing focused light rays, these cameras capture the entire "lightfield", with information about the direction of each ray - which, after applying some digital processing allows us to refocus the image at any point of our choosing.
... Well, as they say, a picture is worth a thousand words. See the following photos, and click on different point of the image to see it in action. :)
Impressive! Now we just have to wait to see how much these Lytro cameras will cost (for now they only say it will be between $1 and $10,000.
But, until then, be sure to check their refocable photo gallery.
